"\VILLIAM LINTER-N, OF CLEVELAND, OHIO, ASSIGNOR OF ONE-HALF TO THE NICHOLS- LINTERN COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

VENTILATOR.

To all whom it may concern:

Be it known that I, VILLIAM LINTERN, a citizen of the United States, residing at Cleveland, in the county of'Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a ventilator particularly adapted for use in vehicles as, for example, railway cars, street cars, omnibuses, limousine automobiles, etc.

The primary object of the invention is to provide such ventilator in a form which shall insure a thorough and frequent change of air within the vehicle without causing troublesome drafts to enter through the ventilator.

The invention may be best summarized as comprising the means by which I accomplish this object, and otherwise increase the efficiency of the ventilator, as hereinafter more fully explained and as set out in the claims.

The drawings disclose my invention embodied as a street car ventilator. The particular form shown, as well as the broader essentials of the invention, is comprised within my invention.

As shown in the drawings, Figure 1 is a perspective view of my ventilator detached; Fig. 2 is a plan of the same; Fig. 3 is a front elevation; Fig. 4 is a vertical cross section of the ventilator; Fig. 5 is a cross section of a portion of the clear story of a street car showing an end view of my ventilator in place; Figs. 6 and 7 are details illustrating the crimping together of various plates of the ventilator.

Referring first to Fig. 5, 10 represents the lower deck, 11 the upper deck, and 12 the vertical wall between the decks, of a street car roof. 20 indicates my ventilator, which is a self-contained structure, here shown as secured to the inner side of the wall 12 and standing partly within the car and projecting partly outwardly, through the opening usually occupied by the clear story window, into the space between the lower deck and the overhanging upper deck.

My ventilator has a frame plate 21 adapted to stand vertically and be secured against a proper supporting wall, as the wall 12 in Fig. 5. On the outer side of this plate is a Specification of Letters Patent.

continuous outwardly extending guard, designated 22. This guard is shown as a vertical plate secured to the plate 21 near its ends and extending in an are from one point of securement to the other. It is to be understood, however, that, in place of extending in an arc, this guide plate might take another course, as, for example, it might have three portions at right angles to each other, making with the front plate a hollow rectangular projection.

Between the front plate 21 and the outstanding guard 22 are a pair of substan tially horizontal plates 25 and 26, as shown more particularly in Figs. l4. These plates connect the front plate with the guard near their top and bottom edges respectively. These intermediate plates 25 and 26 terminate short of the end of the guard so that within the guard at the ends are open spaces in communication with the space between the horizontal plates. An aperture 27 is made in the front plate between the two horizontal plates and extending lengthwise for nearly the length of those plates.

.On the front side of the front plate is formed an upwardly extending deflector which consists of the plate 28 secured to the front plate near its lower edge and extending diagonally upwardly so as to leave a considerable open space between the top of the deflector and the front of theplate 21. At its ends, this deflector is connected with the front plate by end pieces 29.

From the above described construction it will be seen that there is a large open passageway provided from the interior of the vehicle to the exterior through the ventilator, such passageway extending downwardly through the space between the top of the deflector and the front plate, then outwardly through the aperture into the space between the horizontal plates, the front plate and the guard, and thence upwardly and downwardly to the outer air between the front plate and guard and beyond the ends of the horizontal plates. Now, when a vehicle having such a ventilator as described is moved, the outside air is, to a certain extent, compacted at the front end of the guard and correspondingly rarefied at the rear end of the guard, causing an outside longitudinal draft through the space between the horizontal plates, which draft causes an outward draft from within the veflanges.

hicle over the top of the deflector and through the aperture in the front plate. The result is that the vitiated atmosphere within the vehicle is continuously drawn outwardly through my ventilator as the vehicle moves.

It will be noticed that the cross section of the air passageway at the top of the deflector, the aperture through the front plate, and the air passageway outside of the front plate are all correspondingly large, so that much air may pass out through this ventilator. On the other hand, the ventilator is so formed that, when the car is standing, or when there are sudden gusts of wind, there is still. very little chance for a draft to come from the outside of the vehicle into the interior. Any draft which does come, under the circumstances, is deflected toward the roof of the car and dissipated.

It is convenient to make my entire ventilator of metal, the various plates being stiffened by bent over edges. Thus, as shown, the front plate 21 is a piece of metal bent over onto its outer side along the top 30 and bottom 31 and at its ends 32 and also around the aperture, as indicated by 33. The guard 22 is shown as a piece of metal bent over toward the front on its top 35 and bottom 36 and its extreme ends 37 are shown as tucked under the end flaps 32 of the front plate. The top horizontal plate is flanged upwardly at its inner and outer edges and the bottom plate flanged downwardly at its corresponding edges, these flanges tucking under the respective turnedover edges 30 and 35 of the front plate and guard. The extreme ends of the intermediate plates may be bent over onto the inner face of these plates.

The deflector 28 is shown as having its front plate bent near the base of the diagonal portion, as at 38, directly toward the front plate and then bent downwardly and upwardly in a til-shape 89 around the lower edge of the front plate. The top of this deflector plate is shown as having an inwardly projecting flange 40, which is preferably a doubled thickness of the metal. The ends of the deflector are shown as Vshaped pieces flanged forwardly at their up and down edges to lie on the front side of the front plate and the rear side of the deflector plate and these ends are shown as having inwardly projecting doubled top The ends 41 of the deflector front may be crimped around the front flanges of the end pieces 29, as shown in Fig. 6.

WVhen such a construction as described is soldered together at the various joints, a very strong device is provided and one which is extremely neat in appearance. The overhanging top flanges of the deflector front plate and ends not only stiffen these members, but tend to break up any draft co1ning in from the outside through the aperture in the front plate. It is to be understood that the structure thus specifically described, while it is included within my invention, is given in detail simply as one form of embodying the invention. 1 do not desire to limit myself to any particular form further than the state of the art in ventilators requires.

My ventilator is not only extremely effective in service, as practice has demonstrated, but it is very simple and cheap in construction, is neat in appearance, is durable, and is one self-contained device, enabling its very easy application to existing vehicles. Attention may be called to the fact that the aperture through the front plate is entirely hidden from view by the deflector so that passengers are not rendered uneasy by mental suggestion of drafts.

Having thus described my invention, what I claim is:

1. In a ventilator, the combination of a plate with an aperture, a guard on the outer side of said plate having a portion standing some distance beyond it, and end portions connected with it and spaced members connecting the guard with the plate and terminating short of an end portion of the guard.
